Number of planets in our solar system is?
Question:
Answer:
In order of their distances from the Sun, the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Six of the eight planets are in turn orbited by natural satellites, usually termed "moons" after Earth's Moon, and each of the outer planets is encircled by planetary rings of dust and other particles. All the planets except Earth are named after gods and goddesses from Greco-Roman mythology. The three dwarf planets are Pluto, the largest known Kuiper belt object; Ceres, the largest object in the asteroid belt; and Eris, which lies in the scattered disc.
IAU decision and the "Great Pluto War"
The debate came to a head in 2006 with an IAU resolution that created an official definition for the term "planet". According to this resolution, there are three main conditions for an object to be considered a 'planet':
1)The object must be in orbit around the Sun.
2) The object must be massive enough to be a sphere by its own gravitational force. More specifically, its own gravity should pull it into a shape of hydrostatic equilibrium.
3) It must have cleared the neighbourhood around its orbit.
Pluto fails to meet the third condition. The IAU further resolved that Pluto be classified in the simultaneously created dwarf planet category, and that it act as prototype for a yet-to-be-named category of trans-Neptunian objects, in which it would be separately, but concurrently, classified.
eight.
The International Astronomical Union last August made the formal definition of "planet", which did not include Pluto, a body that had long been considered one. We're down to eight.
Some either do not know of the resolution or realize that the IAU is the authority here will say nine.
eight. There were nine before Pluto lost it's status.
8. Pluto is now classified as a dwarf planet.
Our solar system has eight planets only.
Is it clear?
There are now officially eight, as Pluto has been excluded. They are now, in ascending order of distance from the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
8 planets, because pluto is remove from the list of solar system.
eight planets are mercury, earth, marsh, venus, jupiter, uranus, neptune and saturn.
Eight planets because On Aug. 24, 2006, the International Astronomical Union voted to make Pluto a dwarf planet. New definitions were written for planets that excluded the formerly ninth planet.
Immediately following the August vote, Mark Sykes, director of the Planetary Science Institute in Tucson, led an effort to gather more than 300 signatures from planetary scientists worldwide on a petition asking that Pluto be reinstated as a planet. Multiple projects nationwide took off seeking to return Pluto to its planetary status when the union meets again in 2009.
its eight because Pluto is not counted
there are 8 planets in our solar system...pluto has benn discarded.
It was 9 before , then we started finding more and more of planets the size of pluto so it's like we found more than 10,000 planets in our solar system .
so pluto is no more considered as a planet .. AND at present we have only 8 planets...

Our solar system has 9 planets. Though, Pluto is considered as a dwarf planet, but the scientists had revealed anothr startling fact that there is one more planets like earth with is called twins of earth.
I hope it would be clear to you.
Eight .
Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
Neptune

eight pluto is not there.
currently, there are eight planets in our solar system namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. there were nine before but later the scientists said said pluto did not satisfy the condiditons of being termed as a planet. so pluto was voted out of the list of planets.
so now there are only eight.

was nine . at present eight. may be in furure 13 (though an unlucky number )
astronomers are considering Pluto & four more planet like bodies to be included.

now Pluto is re-classified as a large meteor and it is no longer a planet. thus the no. of planets in the solar system now are only eight
